surfaces, with the result that sticking or squeaking of springs will be unknown.

My construction also increases the range of operation of the springs-by freeing the leaves from frictional engagement with each other and adds to 'the life of the springs by assuring that each leaf will travel to the full extent required-of it and that all leaves will recover with equal facilit I believe that parts may be used Without the Whole with certain advantages and that modifications may be made within the scope of the appended claim without departing from the principle or sacrificing the advantages of the invention.

Having carefully and fully described my invention What I claim by Letters Patent is:

A spring cup formed in the end of certain of said leaves and provided with a plurality of perforations, a movable anti-friction bar member Within each said cup and having its ends reduced and wire members extending over said reduced. portions and through said perforations for retaining said members Within their respective cups as and for the purpose set fortlr' r Signed at New York city, New York, this 29 day of Aug, 1916.
